The team from the University of Liverpool and the National University of Ireland Galway have shown that, although penicillin does not kill the bacteria, it does weaken their virulence, making it easier for our immune system and other antibiotics to eradicate the infection. The research findings, funded by the Health Research Board and the Medical Research Council, are published today (15 November 2016) in the Journal of Infectious Diseases.http://medicalxpress.com/news/2016-11-simple-antibiotic-treatment-mrsa-bacteria.html

The research, published online today in the journal Clinical Infectious Diseases, shows that poultry may be a source of human exposure to MRSA, a superbug which can cause serious infections and even death.http://medicalxpress.com/news/2016-09-superbug-mrsa-contaminated-poultry.html

The study, which will be published online August 15 ahead of issue in The Journal of Experimental Medicine, suggests that inhibiting this response may help treat patients infected with both the flu virus and MRSA.http://medicalxpress.com/news/2016-08-mrsa-superbug-influenza-patients.html
